I don’t disagree that it’s a weakness. But that just is how it is for now. I’d guess that it will settle down to a few dozen “strong” instances that are all federated together, with hundreds more smaller instances available, but right now there are like 5 super-packed instances (lemmy.world, sh.itjust.works, kbin.social, etc) which are getting killed with a double-whammy: all the users and all the communities are on them.
Create an account off of lemmy.world and see if you have the same issues. A smaller instance can handle things easier. It have 2 but use the one that was most up-to-date and responsive.
Same here. I have a 9 year account on Reddit with only a few hundred posts and karma; by the time I found something worth posting about anything I posted would either drown out in the noise or essentially already be posted.
Why would you create an account on every server? You can access any community on any server that your server is federated with.
